Welcome to NSO 2011: New Horizons of Discovery

On May 18-21, 2011, the University of Wisconsin-Madison will proudly host the 27th annual National Science Olympiad Tournament. More than 7,000 students, educators, parents and volunteers are expected to attend from across the country.

Our campus and city truly reflect the tournament theme of "New Horizons of Discovery." In 2009, The Chronicle of Higher Education ranked UW-Madison third nationally in the number of university-generated patents. ranked Madison the third best city for science and technology jobs. And The Princeton Review named UW-Madison one of the top 25 entrepreneurial campuses in the nation.

The university and city are excited to provide the perfect setting for a competition that emphasizes science, technology, engineering, and math excellence. We also want you to discover our beautiful campus external and city external. The university has many new facilities housing its wide array of academic majors external. National Science Olympiad competitors will experience many of these great facilities, including Union South external, The Wisconsin Institutes for Discovery external, modern science buildings (ECB, ME, Microbial, Biochem, Genetics/Biotechnology, Pharmacy, Health Sciences, etc.) and the Kohl Center external where the opening and closing ceremonies will be held.

We hope you will come early to take advantage of the many tours, workshops, science career fairs and other activities we have planned. See for yourself why the University is a top-ranked institution and the city of Madison is recognized for offering a great quality of life. We want your visit to be informative, fun and memorable.

This website will be updated right up to the National Science Olympiad Tournament on May 21, 2011. All key tournament registration links will be live by January 2011. In the meantime, please continue visiting for updates.

Understanding Immunity

In the mid-1940s University of Wisconsin geneticist Ray Owen noticed a surprising fact about non-identical cattle twins. Each twin had two kinds of blood cells, its own and those of its twin. In ordinary transfusions, such mixing of blood cells often leads to severe immunological reaction. Owen realized that when bloods are exchanged early in development, each twin somehow learns to tolerate the other's cells. This discovery of "immune tolerance" helped to explain how an organism can tell its own cells from foreign ones, and fueled a revolution in immunology. The nature of immune tolerance is central to studies of organ transplantation, cancer, and autoimmune diseases.
